Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we’re thankful for turned out to be what they are.

1. Most historians hold that the Chinese invented fireworks in the 9^th century when they discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.

2. In May of 1886, a law led John Pemberton, a pharmacist(药剂师), to rewrite the formula(配方) for “Pemberton’s French Wine Coca”, his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated(碳酸) water. His bookkeeper suggested the name Coca-Cola because he thought the two C’s would look good together, which is how what we call Coca-Cola, a world-wide drink came into being.

3. During World WarⅡ, scientists at the University of Birmingham invented the magnetron(磁控管)—an important heat-producing part of the microwave oven. While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels(仁), and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.

Nora, a 17-year-old American, notices that when she has to do a paper for school and researches it on the Internet, she rarely reads a whole page and does deep reading. “I’ll read the beginning of a paragraph and then I'll skip(跳过) the rest,” she says.

   While Nora's mother, Martha, loves sitting down with a good book and reading carefully, her daughter may be the wave of the future.

  “Deep reading”, or slow reading, is a process in which people think carefully while they read. With most, that means slowing down --- even stopping and rereading a page or paragraph to really understand what the author is trying to say.

   Last summer, Google CEO Eric Schmidt said he was concerned about what he sees as a decline（衰退）in slow reading. Instant messages and 140-character tweets（微博）appear to be reducing out ability to concentrate on a single idea or theme of a book, he told Foreign Policy Magazine.

   It's easy to forget the benefits of deep reading in an age when anything worth doing is done fast. Experts warn that without deep reading, it is impossible to be an educated person of the world, a knowledgeable voter or even an imaginative thinker.

  “If you want to have a deep relationship with a text and understand a complex idea, then slow reading is a preferred style. It is good for pleasure, too. It is not a rushed experience and you can lose yourself in a text,” said Canadian writer John Miedema, the author of the book Slow Reading.

  US' Ohlone College English professor Cynthia Lee Katona says reading is a highly social activity that builds the mind and social connections. If you read, she says, you simply know more and have more to talk about with friends, partners and people you know.

   Deep reading can also take a reader on a trip around the world even if they are sitting in a living room armchair, Katona says. Also, deep reading helps people develop thinking, writing and conversation skills.

  “If you like beautiful things, authors put words together that are really beautiful and expressive,” she says. “If you want to write well--- and there are lots of reasons to express yourself clearly --- you should read.”
